To all whom it may concern:

Be it known that I, FRANCIS LEE STUART, a citizen'of'the United States,and a residentof the city of 'Washington, in the Distric't of Columbiahave invented certain W new and useful Improvements in Reclaiming andConveying Apparatus, of which the following is a specification.

"This invention relates broadly 'to conveymg apparatus, and moreparticularly to an apparatusof this type adapted for reclaiming materialfroni'storagc and transferring the same to any desired point where itmay belo'aded lfortrahsportation. The'object of'the present invention isto provide an" apparatus of this type comprisin a reclaiming conveyoradapted to reo'elve material from a digger of any desired "constructionwhich is adjustable longitudi- 80 nally thereomand deliver the same to atraveling carrier by which it may be transferred to final' loadingposition. T-his applicationis a division of my copending application,Serial No. 201,798 filed Nov. 13, 1917, and the claims herein areconfined to the novel features of the re claiming conveyer andlongitudinally adjustable digger before referred to.

My improvements are illustrated in the I0 accompanying drawings, inwhich Figure 1 is a plan view diagrammatically illustrating atransferring system employingmy improved reclaiming apparatus.

'OOaLMOI'B and thelike fromstoragepi'les' "which have preuiouslbeenstookedtfromia amain SOllI'BInOiSllPP y. In order to reach all parts-ofithe fstoragetpile it has been found desirable to provide a reclaimeror reclaiming conveyer which is bodily adjustable longitudinally of atraveling carrier, andwhlch in turn is provided with an independentlyadjustable traveling digger for engaging the material n thepile andelevating the same to a position on there,-

claiming conveyeri t a v Referring more draw:

ings, I have illustrated atransferring sys M tern employing a travelingcarrier lnof 'lny' desired construction, here illustrated as be ing abelt conveyor. The carrier 1 may be supplied directly with material froma" main source, and depositthc saine in suitl0 able storage piles S bymeans of trimmers 2 constructed in the manner described in my Patent No.1,241,053, of Sept. 25 1917. On the other hand, if desired, the materialmay be transferred by the carrier 1 directl 0K to care C, or otherreceptacles to be loaded: and deposited therein by loading trimmers 4 ofany desired construction.

It frequentl r happens that the main A source of supply becomesexhausted before 10 the cars 0 are completely filled. In such cases thereserve supply in the storage piles S ,is utilized through the medium ofthe reclaiming conveyer R hereinafter more fully described. In itspreferred form the re- 75 claiming conveyor comprises a main truck 5carried on wheels 6 traveling on the rails 7 which are preferablydisposed in. pit 8 below the main surface of the adjoining storagepiles, The trackway 7 is so disposed that it straddles the travelingcarrier 1 which is preferably disposed with its upper run carried ,bytroughing rolls 9 and its lower run on supporting rolls 10; A motor 11is provided for propelling the truck "5 to operative position alon thetrackw'ay.

Mounted centralll' o the truck 5 is a turn-table 12 rotata ly'carriedbythe anti friction rolls 14, Extending centrally through the turn-tableand {truck is a hopper .0 15 having its lower end 16 disposed in discharging relation with the upper run of the traveling carrier; Supportedat one end in the turn-table" 12 is 'a'- trussed- -frame 17' mounted atits opposite end on wheels 18 having-their axes so disposedthattheentire frame may i be rotatably adjusted relatively tothe tru'ck5 by the motor 19. 'Thismotor is 'pleferably-positioned' on the outerend of the frameworkjsouthatithequ riwer developed thereby is.:eflZective more directly in producing the swinging movement of theframe, Mounted on the frame 17 of the reclaims! is a second conveyor 20,which is preferably a belt conveyor adapted to be 108 driven b 1 a motor21 mounted within the frame, lls 22;disposed adjacent oppositeends ofthe frame serve to guide the endless conveyer, one of these rolls actingas a discharging or tripper roll for delivering to the hoppen 15.

Extending longitudinally of the frame 6 are tracks 24 having their ends25 upturned to constitute stops.

Adapted to travel on the rails 24 is a truck 26 having flangedsupporting wheels 27 and driven by-a suitable motor 27'. The truck 26 isalso provided with a turn-table 28 mounted on anti-friction rolls 29.and provided with an operators station 30. A hopper 31 having itsdischarge 32 disposed to deliver material to the conveyer 20 in thedirection of its travel, is mounted on the turn-table 28. This hopper issupplied. with material directly from the storage piles by an inclinedelevating digger or the like 34 mounted in a frame-work 35. \Vhere anendless digger is employed it is adapted to pass around a guide roll 36at its lower end 'and a tripper roll 37 at its upper end. An independentsource of power 38 may be provided for driving the digger.

Although by disposing the truck 5 in a pit and thereby causing the upperportion of the frame 17 to extend in a substantially horizontal planemost of the material may be effectively reached, it sometimes becomesnecessary to provide means for reaching material at a still higherlevel. This may be easily accomplished by providing extensions 39 on thetruck 26 and equipping the same with hand-wheel adjusting devices *0 85of any tvell'known form so that the digger may be raised to dotted lineposition, as

clearly shown in Fig. 3 of the drawings. From the foregoing. it isbelieved that the operation of my improved reclaiming 40 andtransferring apparatus will be obvious.

The truck 5 after having been moved to desired position along thetrackway serves as a pivotal support for the reclaimer' R.

This reclaimer may in turn be swung into 46 a position in winch thedigger 3* will opcrate. on the material. and the digger may beindependently rotatable and longitudinally adjusted with relation to thereclaimer. It will be apparent that the digger is operative on eitherside of the reclaimer at will, ad-

justment from one side to the other being accomplished. by moving thetruck 26 to 1ts extreme outer position on the tracks 24 and thenswinging the digger. as desired. By 66 reason of this constructionmaterial in storage may be easily and quickly reclaimed and delivered totransferring means by which it is readily loaded for shipment.

Inasmuch as changes may be made in the 80 structural embodiment of myimproved apparatus, it is desi ed that the drawings be considered onlyas illustrative of the preferred form. V

In my application for patent Serial No. 66 201,798, filed Nov. 13, 1917,I have shown a turn-table, and means for adjusting said digconveyingsystem comprising a main conveyer belt, a track parallel therewith. atruck supported on said track. a motor for driving said truck, aturn-table carried by the truck and provided with a hopper delivering tosait main conveyer belt, and a boom conveyer supported at its inner endby said turn-table delivering through the hopper to the main conveyerbelt and which is pivotally mounted at its inner end to move about ahorizontal axis whereby the outer end of the boom conveyer may beelevated and sn'ungfrom one side of the track to the other to gathermaterial on either side thereof. I have also shown in said applicationSerial No. 201,7 98 a digger carried-by the boom conveyor and adjustablerelatively thereto about a vertical axis, and also a power-driven truckon the outer end of the boom. I therefore make no claim in the presentcase to such subject matter.

I claim as my invention:

1. An apparatus for reclaiming material from. storage and conveying thesame to devices to be loaded, comprising a main receiving conveyer, aconveyer adj ustable longitudinally of said receiving conveyer andarranged to discharge material thereto, means for rotatabl y adjustingsaid conveyer about the point of discharge, a digger rotatably mountedon said conveyer for supplying ma terial from storage thereto, and meansfor moving the same longitudinally of the conveyer.

A reclaiming apparatus comprising asupporting truck, a turn-table carried thereby, a reclaiming conveyereupported at one end on said turn-table,' a mot-or on the opposite endof the reclaiming conveyer for swinging the same about the turn-table, atrackway extending lqngitudinally of the reclaiming eonveyer, and adigger adjustable along the traekway.

6. A reclaiming apparatus comprising a. truck. a turn-table thereon, .1reclaiming conveyor supported at one end on the turntable. a trackwayextending along said reclaiming ronveyer, and a vertically and rotatablyadjustable digger on said trackway.
